.,N. `Y.,.. A- CORPORATION 0F NEW VIl' ERSIEY HEAD PROTECTOR Application `filed December 23,1929. Serial No. 415,943.

Our invention relates to new and-useful Another object isto provide for the trans-l parent medium a protectingfscreen whiehmay m be easily and' quickly removed tol permit cleaning of'tlie transparent medium.

The `invention consists in the improved construction andv combination of parts, to'be morev fully describedV hereinafter, and the novelty of'which' will be particularly pointed out and'distinctly claimed.

l lIn the accompanying drawing to be taken asa part` of this specification,y we have fullyA and, clearly illustratedv a preferred vembodiv4211 ment` of four invention7 in which drawing--Y Figu'rel is aview in front. elevation of a helmet or head1 protector embodying'4 our in'- vention;

. Fig'. 2'is a'view'in front elevation, and partially in section7 with the" front screen mem'- ber removed, and

tectorcomprising a helmet proper 2 to the ofllfig. 1". Y l y v j "Referring: t0 the drawing by characters of reference, 1? designates7 generally7 a head proe'd'ge orfbrim of which is sealedaj depending capemember-B, preferably of leather. In the frontv ofthe' member S'is a sightopening 4,.

which isA preferably substantially Vrectangular7 ,and thev top edge -of which is lformed by' tliehelmet brim.,` AOverlyingY the member 3 along.E the periphery of' opening 4 is aframe' or plate member 5,1 preferably of metal, `having at-` its topa rearwardlyv extending portioniwhichvis inclinedto the plane ofthe' frame member and which lies upon and conforms vto the helmet brim `to whichit is secured by rivets, orthe like?. The cape mem-` ber;3" is sealed tightly to the member V5 by a substantially rectangular frame clamping member 8^having an inner ma-rginal Vflange 9 which extends through openingfl and is fixed alongits edge tomember 5, asat 10byfsolder, orfthfe like;v Through the member 5' is a sub- Fig; Sis a view in'section on theline 3 3 stantially rectangular opening 11-which registers withl opening 4,'and surrounding thev opening 11 the member 5'hasA a recess which may be stamped out from the plane ofy the plateV member providing va transverse flange portion' 12 anda shoulder or seat portion 13'.` ClosingY and sealing the openings t'andvll, is'

a transparent member or medium 14,' preferably glass', which is'positioned. within the"l flangeportion 12 and seats' against the vporthe recess byl a rectangular 'frame 15 which may bejournaled'atitstop on pins 16 vseating 1n opposite; apertures 17 inf. the' portion l2. Gaskets I8 I of rubber,- or 'the like,l are prefer-V ably providedV to seal the joint between the! medium 14 and member 5 andfto resiliently cushionv theframe 15. At the. bottom of overlying and clamping engagement withY the bottomportionv of frame 15. i

f Ojn the'outside of'member 5'and on each sideof opening 1l, are'vertica'lly entending supporting'angle members 21which preferably eXtend above and belowopenin'g 11. One flange of' each member-21' is secured to member 5'I'byV bolts 23 which are passed through the "clamping member Sand servelto clamp member'be'tween members 5 and ,8i The'remainingfflanges 24 of angle members 21y 'extend forwardly from member 5. Through flanges 24above opening 11 are alined" apertures 25, and'l through y flanges 24:l below opening v11 are alined apertures v26. Clamped between' member 5 and flanges- 22 is. thevertical flange 27 of an angle member 28,' the yother flange 29 of which extends horizontally forward overand laterallybeyond the flanges V24 to serve as a light 'shieldfl Overlapping and closely adjal centithev flanges2lr and substantially4 parallely to the planes thereof, are vertical flanges 30 as flanges 24- and have alined apertures 32 Vat the top thereof and alined apertures 33 at the bottom thereof, which register with apertures and 26 respectively. Extending through apertures 25 and 32 is a hinge pin or member 34 which secures the anges 24 and together at their upper ends. Extending through apertures 26 and 33 is a pin or member 35 which secures the flanges 24 and 30 together at their bottom ends. The members 34 and 35 are provided at one end with extensions or loops 36, 37, respectively7 which serve as hand grasps for removal and insertion of the members, and which also serve as stops to limit the inward movement on insertion of the pins or members into the apertures. On the front face of member 31 is a frame or plate member 38 which is secured to member 31 by bolts and nuts 38 or the like. Through members 31 and 38 is an opening 39 which registers and is substantially coextensive with opening 11. The opening 39 is closed by a screen member 40, preferably of fine wire mesh, which extends and is tightly clamped along its periphery between members 31 and 38. The plate member 38 extends laterally beyond and below the frame members 5 and 31 and above the angle member 28 and member 31 to protect them from injury or distortion by missiles. The front face of member 38 is covered by a resilient cushioning member 41, preferably of rubber, so that the blows of missiles impacting the same will be cushioned.

When the head protector is worn by an operator engaged in sand blasting, or like operations, the air is filled with dust' which settles on the glass or transparent medium 14 obscuring the visionl of the operator. When this occurs, access to the glass or medium 14 for cleaning is obtained by removing the pin 35 and swinging the screen member and its frame upward on the pin 34, thev angle member 28 being of resilient metal which will bend to permit lifting of the screen member. If desired, the screen member and its supporting frame may be detached from the head protector by withdrawing both of the pins 34 and 35,. It will thus be seen that the glassy or medium 14 may be cleaned without the necessity of the operator removing the protector, or the transparent sight opening sealing medium 14.

What we claim and desire to secure by Lety ters Patent of the United States is:

1. A head protecting device comprising a head enclosing member having a sight open.- ing, a transparent medium sealing said opening, said member having supporting means at v, the sides of and above and below said open- G0 ing, a frame member having supporting means above and below said opening and `cooperable with said first-named means to space said frame member from said enclosing mem- ,.6.: ber, said first-named and said second-named means having alined apertures above and below said opening, horizontally positioned pins extending between and through said apertures to secure said members together, said frame member having an opening registering with said sight opening, and a screen member closing said second-named opening.

2. A head protecting device comprising a head enclosing member having a sight openmg, a transparent medium closingsaid opening, substantially vertical flange members .extending forwardly from said member at the sides of said opening, a frame member having rearwardly extending substantially vertical flange members cooperable with said firstnamed flange members, a hinge pin extending between said first-named flange members adjacent the upper ends thereof and through alined bearing apertures in said first and said. second-named flange members to secure said frame member to said enclosing member and whereby said frame member can swing upward and outward on and from said firstnamed flange members, said frame member having an opening registering with said sight opening, and a screen member closing said second-named opening.

3. A head protecting device comprising a head enclosing member having a sight opening, a transparent medium closing said opening, substantially vertical flange members extending forwardly from said member at the sides of said opening, a frame member having rearwardly extending substantially' vertical flange members cooperable with said firstnamed flange members, a hinge pin extending between said first-named flange membersV adjacent the upper ends thereof and through alined bearing apertures in said first and said second-named flange members to secure said frame member to said enclosing member and whereby said frame member can swing on said first-named flange members, said frame member having an opening registering with said sight opening, a screen member closing said second-named opening, and means to hold said screen member and said transparent medium in substantially parallel relation. y

4. A head protecting device comprising av Ido ifa

ifo

head enclosing member having a sight open-` n..

ing, a frame member surrounding said opening, a transparent medium secured to s'aid iis Erst-named anges, said forwardly and rear- Wardly extending Hanges having alined top and bottom apertures, and pinmembers extending through sad apertures to secure said plate members to said frame member.

In testimony whereof We have hereunto signed our names.
